Trust planning for crypto millionaires in the UK is not a niche exercise for the future. It is an urgent, present-day necessity for anyone who has built substantial wealth in digital assets and now calls the United Kingdom home. Cryptocurrency, NFTs, DeFi positions, and tokenized assets have created a new class of millionaire—often young, globally mobile, and holding wealth in a form that traditional estate planners barely understand. When a crypto investor passes away without a properly structured cross-border estate plan, the result is not merely a tax bill. It is a scramble for private keys, a forced liquidation during a market trough, a dispute between heirs across multiple jurisdictions, and the potential total loss of assets that were never recorded in any conventional registry.
At Jungle Tax, we specialize in helping crypto-wealthy families design trust and inheritance structures that work across both the United Kingdom and the United States. This guide explains why trust planning for crypto millionaires in the UK demands a completely different approach from traditional estate planning, how the UK’s inheritance tax regime applies to digital assets, and what structures—from excluded property trusts to US grantor trusts—can protect your crypto wealth for the next generation.
The very features that make cryptocurrency revolutionary—decentralization, private key control, and cross-border fluidity—are also what make it an inheritance nightmare. A Bitcoin wallet does not pass through probate automatically. There is no bank to contact, no central register to notify, no automatic transfer mechanism. If the private key dies with the owner, the asset is irretrievably lost. Even when the heirs possess the key, accessing a wallet may violate an exchange’s terms of service, trigger anti-money-laundering freezes, or fall foul of laws in the jurisdiction where the exchange operates.
For trust planning crypto millionaires in the UK, the first step is not tax optimization; it is asset survival. A trust structure solves the access problem by holding the private keys, or the right to direct them, in a legal entity that continues after the settlor’s death. The trustee—acting under a clear, legally binding set of instructions—can secure the wallet, manage distributions, and ensure that the assets are not lost in the chaos of bereavement. Without a trust, even a meticulously drafted will is insufficient, because a will is a public document, and revealing private key information in a public probate filing is both a security risk and a privacy violation.
The same concerns apply to non-fungible tokens, liquidity pool positions, and staking rewards. Each of these is a form of intangible property that may be located, for tax purposes, wherever the owner is domiciled, or wherever the smart contract is deployed, or wherever the issuer is incorporated. The UK’s conflict-of-laws rules for digital assets are still evolving. Still, the Law Commission’s recent work on digital assets as a distinct category of property confirms that they can be held on trust. This makes trust planning for crypto millionaires in the UK not just advisable but essential.
The United Kingdom imposes inheritance tax (IHT) at 40% on the worldwide estate of a UK-domiciled individual. Cryptocurrency, as property, falls squarely within the charge to IHT. If a UK-domiciled crypto millionaire dies with a portfolio worth £10 million, the estate faces a potential IHT bill of approximately £3.4 million, after the nil-rate band and any residence nil-rate band. That tax is due within six months of death, before probate can be granted and before the estate can be distributed to heirs. For an estate that consists primarily of volatile digital assets, forced liquidation to pay the tax can destroy significant value.
For the crypto millionaire who is not UK-domiciled—for example, a US citizen who moved to London three years ago—the situation is different but no less complex. A non-domiciled individual is generally subject to IHT only on UK-situs assets. The situs of cryptocurrency is not definitively settled in UK law, but HMRC’s view, expressed in its Cryptoassets Manual, is that cryptoassets are located where the beneficial owner is resident. This would place them outside the UK IHT net for a non-domiciled individual, provided the assets are not held through a UK-registered entity. However, the non-domiciled status is temporary; after fifteen years of UK residence, an individual becomes deemed UK-domiciled, and worldwide assets become subject to IHT.
Effective trust planning for crypto millionaires in the UK can neutralize this exposure. A non-domiciled individual can settle non-UK situs assets—including cryptocurrency—into an excluded property trust before becoming deemed domiciled. Once the trust is established and funded, the assets fall outside the UK IHT net permanently, even after the settlor acquires deemed domicile. This is the single most powerful IHT planning tool available to crypto investors who have recently arrived in the UK, and it must be executed before the fifteen-year clock expires. Our guide on streamlined filing for HNW Americans in the UK explains the parallel income tax compliance issues that often accompany these structures, ensuring that the trust is not only IHT-efficient but also fully compliant with US reporting obligations.
For many crypto millionaires, the tax equation involves more than one country. A US citizen who has accumulated crypto wealth while living in the UK faces simultaneous exposure to the US estate tax, which applies to worldwide assets, and the UK inheritance tax. Relief methods are provided by the US-UK Estate and Gift Tax Treaty, but they must be actively pursued through properly constituted trusts and treaty reports.
The most effective trust planning strategies for crypto millionaires in the UK frequently deploy one of two structures. The first is the UK excluded property trust for the non-domiciled settlor, as described above. The second is the US revocable living trust, which ensures that crypto assets held through the trust avoid the notoriously slow and expensive US probate process. For a US citizen, a revocable trust does not remove assets from the US estate tax net. Still, it solves the probate problem and, crucially, provides a governance framework for digital asset management after death. The trust instrument can include specific powers for the trustee to manage crypto wallets, stake tokens, and liquidate positions according to a pre-defined plan, rather than leaving these decisions to an executor who may have no understanding of the technology.
Where a crypto millionaire has heirs in both the US and the UK, a dual-trust structure may be appropriate: a UK excluded property trust for non-UK-domiciled settlors to hold assets outside the IHT net, and a US revocable trust or a US grantor trust to hold US-situs assets or to benefit US-resident heirs. The coordination of these trusts must account for the US throwback tax rules, the UK’s tenth anniversary charge for relevant property trusts, and the US information reporting obligations on Forms 3520 and 3520-A. These are intricate, technical areas, and the cost of getting them wrong is severe. Our trust planning guide for accidental Americans with family wealth illustrates the same cross-border trust dynamics in the context of inherited family wealth, and the principles apply equally to crypto fortunes.
One of the most overlooked aspects of trust planning for crypto millionaires in the UK is the selection of the trustee. A traditional trust company or a family solicitor, however competent in conventional asset management, is rarely equipped to handle the security and operational demands of digital assets. The trustee must be able to securely store private keys, manage multisignature wallets, interact with smart contracts, and navigate the regulatory landscape of crypto exchanges. Some families solve this by appointing a trusted individual—often a tech-savvy family member—as a co-trustee or a protector with specific powers over digital asset management. Others engage specialist crypto custodians who operate under regulated frameworks and can be instructed by the trustee. The key point is that the trust instrument must expressly authorize the trustee to hold and manage digital assets, and it should provide a clear investment policy statement that sets out the parameters for risk, staking, lending, and liquidity.
Consider the case of Liam, a blockchain entrepreneur who built a successful DeFi protocol while living in San Francisco. At 35, he moved to London with his British wife and two children. His wealth consists primarily of tokens issued by his protocol, a portfolio of ETH and stablecoins, and several high-value NFTs. He is a US citizen, currently non-UK-domiciled. Without planning, his worldwide estate would be exposed to both US estate tax and, once he becomes deemed UK-domiciled, UK inheritance tax at 40%. His assets are volatile, and his wife has no technical understanding of how to access the wallets.
Liam’s trust planning crypto millionaires in the UK strategy involves two key steps. First, before he reaches deemed domicile, he settles his non-UK tokens and NFTs into an excluded property trust with a professional trustee, removing them from the UK IHT net permanently. Second, he establishes a US revocable living trust to hold his US bank accounts and any remaining US-situs assets, ensuring that probate is avoided and that a trusted tech-savvy co-trustee can manage the digital wallets. The trust instruments include detailed digital asset management provisions, and the corporate documents for his protocol company are aligned to ensure that control of the protocol passes smoothly to his heirs. This integrated approach, which we have also applied in our cross-border estate planning for private equity executives and estate planning for entertainers with global income, demonstrates that digital wealth can be protected with the same rigor as traditional assets, provided the structures are put in place before a crisis.
A trust that holds cryptocurrency must file annual tax returns. Valuing the assets, calculating gains on disposals, and reporting staking income and airdrops are all complex areas that require specialist knowledge. The UK’s Cryptoassets Manual and the US IRS guidance on virtual currency both treat crypto as property, not currency, so each disposal—including a transfer to a trust or a distribution to a beneficiary—is a potential taxable event. A properly structured trust will account for these tax events in advance, ensuring that liquidity is available to pay any tax that falls due and that the trust’s reporting obligations are met.
For US persons, the transfer of crypto to a foreign trust triggers additional reporting requirements under Section 6048, and the trust itself may be subject to the throwback tax regime if it accumulates income. These US rules apply even when the settlor and the trust are entirely UK-based, because the settlor remains a US citizen. The intersection of US tax rules and UK trust law is where trust planning for crypto millionaires in the UK becomes most technical, and where the guidance of a dual-qualified advisor is indispensable. We have explored similar intersections in our offshore disclosure guide for London investment bankers and our analysis of the cost of non-compliance for senior law firm partners, both of which highlight the penalty exposure that arises when complex assets are held through unreported offshore structures.

Yes, but the tax treatment depends on your domicile status and the type of trust. For a non-UK-domiciled individual, settling crypto into an excluded property trust generally does not trigger an immediate UK tax charge, provided the transfer is not a chargeable lifetime transfer exceeding the nil-rate band. US citizens must also consider the US gift tax rules and the reporting of the transfer on Form 3520. The transfer itself is a disposal for US capital gains tax purposes, though the foreign tax credit may offset any UK tax due.
Yes. HMRC’s Cryptoassets Manual confirms that cryptoassets are property for IHT purposes. Their situs is generally determined by the beneficial owner’s residence, which means that a UK-domiciled individual’s worldwide crypto portfolio is subject to IHT, while a non-domiciled individual’s crypto held outside a UK structure is typically exempt, until deemed domicile arises.
Your estate will be distributed according to the intestacy rules of your country of domicile. In the UK, this may mean your spouse and children inherit your assets, but accessing crypto wallets requires the executor to locate private keys and comply with exchange procedures, which can be extremely difficult. Without a trust, the executor may be forced to apply to court for directions, and the assets may be frozen or lost entirely.
A revocable trust, such as a US revocable living trust, does not remove assets from the UK inheritance tax net if the settlor remains UK-domiciled and retains benefit. For IHT purposes, the assets are treated as remaining in the settlor’s estate. An excluded property trust, which is irrevocable and settled before deemed domicile arises, is the appropriate vehicle for IHT protection.
If the settlor is a US citizen, the trust’s assets may be includible in the US gross estate, depending on the trust’s terms and the retention of powers. The US-UK Estate Tax Treaty provides a pro-rata unified credit and tie-breaker rules, but treaty benefits must be claimed affirmatively. A dual-qualified advisor can coordinate the trust’s terms to minimize both US and UK estate tax exposure.
